Public perceptions of traumatic brain injury: predictors of knowledge and the effects of education

A psychometric evaluation of a new social subscale for the Common Misconceptions about Traumatic Brain Injury (CM-TBI) questionnaire: toward the CM-TBI-II

OBJECTIVE

Existing TBI misconception measures are critiqued for failing to measure postinjury social experiences. This study developed a social subscale for the Common Misconceptions about TBI (CM-TBI) questionnaire for use in the general public.

METHODS

Seven experts independently review items drawn from the literature. Shortlisted items were administered online to 158 adults (aged ≥18 years; 51% postschool educated; 60% no TBI experience), the CM-TBI, and a measure of construct validity (a published TBI-adaptation of the Community Attitudes Towards the Mentally Ill; CAMI-TBI). One week later, the new items were redeployed (n = 46).

RESULTS

Expert review and iterative correlations identified a 10-item social subscale (internal consistency, test-retest reliability, α's>.80). When added to the CM-TBI (ie. CM-TBI-II), the internal consistency was .71. The social subscale was significantly correlated with CAMI-TBI measures (p's <.05, r's > .3). There was no significant difference on the social subscale for education subgroups (school vs post-school, p = 0.056) or previous TBI experience; but there was a difference for the CM-TBI-II (post-school>school; Cohen's d = 7.83, large effect).

CONCLUSION

This study found strong preliminary psychometric support for a new social subscale, administered as the CM-TBI-II. This subscale shows promise as a measure of misconceptions about social functioning post-TBI. The CM-TBI-II could support evaluations of programs aiming to improve social engagement and community participation for people with TBI.

Level of knowledge and misconceptions about brain concussion in Brazilian adults

BACKGROUND

Brain concussion (BC) is seen as a public health priority due to its high incidence and morbidity rate, among thousands of people around the world. There are needs for fast identification, accurate diagnosis and correct management in order to reduce the short and long-term problems relating to BC. Proper knowledge of BC in the population and among clinicians is a critical factor in achieving this.

OBJECTIVES

To evaluate the level of self-reported BC knowledge and gaps/misconceptions, and to identify variables correlated with this level.

METHODS

A cross-sectional descriptive survey was performed. A Brain Concussion Knowledge Questionnaire (BCKQ) that had been created to capture data was widely distributed. Total scores, domain partial scores and percentages of correct and incorrect answers were calculated to ascertain the level of knowledge relating to BC.

RESULTS

The sample was formed by 1,247 Brazilian adults (age: 41.7±11.8 years). Partial scores of the BCKQ revealed the existence of poor knowledge and misconceptions in all domains of the questionnaire, especially regarding questions about recovery from and management of BC. Moderate correlations between BCKQ scores and professions (p=0.312; P=0.00) or previous brain concussion knowledge (p=0.489; P=0.00) were observed. In a multiple linear regression model, age, profession and sports practice were predictors of BC knowledge.

CONCLUSION

This first study to analyze the level of BC knowledge in a sample of Brazilian adults suggests that poor knowledge and misconceptions are present. Thus, meaningful and useful information was provided by this study for developing health education programs about BC for the population in order to improve fast diagnosis and correct BC management.

Misconceptions about traumatic brain injury among nursing students in India: implications for nursing care and curriculum

Background

Despite the devastating consequences of Traumatic brain injuries (TBIs), TBI misconceptions are common among healthcare professionals. As an essential member of multi-professional team providing TBI care, it is important that nurses have correct information and adequate skills to achieve the best possible outcomes for TBI. For example, some common misconceptions about TBIs are that a second blow to the head can improve memory functioning and wearing seatbelts can cause as many brain injuries as it prevents. In India, perhaps such misconceptions towards TBI among nursing professionals were not yet documented. As nursing students form the future health workforce, understanding TBI misconceptions among nursing students in resource-limited settings like India will provide useful information for strengthening the nursing curricula for improved care and rehabilitation of TBIs.

Methods

We used a cross-sectional survey to study the TBI misconceptions among nursing students in India. A Common Misconceptions about Traumatic Brain Injury (CM-TBI) questionnaire was administered to 154 nursing students from a nursing college of a tertiary care neuro-centre in India. The mean percentage of misconceptions were calculated for 7-domains of CM-TBI. T-test for independent samples and ANOVA were used to study the association of misconception with socio-demographic variables using total score for each respondent.

Results

Of the 143 nursing students who completed the survey, majority of them were female (97%) and in the 19-20 year age-group (95.1%). Domain on brain damage (81.1%) had highest rate, while amnesia domain (42.0%) had lowest rate of misconception. The overall mean-score was 22.73 (Standard Deviation: 4.69) which was significantly higher than the median score of 19.5. The study did not show significant differences on overall misconceptions about TBI for any of the socio-demographic characteristics.

Conclusions

Misconceptions about TBIs were common among nursing students and it was pervasive irrespective of age, gender, place of residence and year of education. A need to strengthen nursing curriculum in the area of TBIs has been emphasized for improved care and management of TBIs. The study findings also suggest the need for understanding such misconceptions among other healthcare professionals involved in TBI care.
